Determine the components of a 5 kN force F acting at point A, in the direction of a line from A to B. Given: A = (2, 3, − 2.1) m and B = ( − 2.5, 1.5, 2.2) m. We will take the solution one step at a time. (a) Draw a good diagram. Weba result connecting the direction cosines of any 3-D vector. In 2-D, we have a similar result without the γ term. In 2-D, it is also clear that cos β = ± sin α, so the direction-cosine identity reduces to cos 2 α + sin 2 α = 1. The 3-D result, Eq. (4.9), is a bit less obvious. Example 4.1.2 Direction Cosines. Let A be the column vector 4 2-4.
